存储器IC卡数据传输的加密研究

摘要

通过对存储器智能卡数据传输特性的分析，指出了明码传输控制的安全缺陷，提出了一种基于单钥加密体制，针对数据明码交换进行加密的原理模型，详细阐述了该模型的加密算法流程、实现手段及其优缺点等．%Through analyzing data-transferred characteristic of memory smart card, security bug of transfer with unencrypted code is pointed out. Based on principle of single key eneryption, a kind of encryption model for unencrypted data-exchange of memory card is put forward. The process, measure, advantage and disadvantage of the model are particularly expounded.
